In the late 1960s, a food industry group called the Sugar Research Foundation paid three Harvard researchers US$6,500 (about US$50,000 today) to discount research that increasingly showed links between sugar and heart disease and to point the blame at fat instead, according to an analysis of historical food industry documents published in fall of 2016.

The report those Harvard scientists published transformed the American diet, causing people to steer clear of fatty foods, which led many to sugar-packed snacks instead. But as a significant body of research now shows, excessive sugar consumption can be devastating for our health.

Even though we're now more aware of the risks of too many sweets, there are still plenty of myths about sugar and what it actually does to us.

After all, sugar is just the name for a simple carbohydrate, and there's always been some sugar in our diets.

The problem is that today the average American consumes more than twice what the US Food and Drug Administration (FDA) - and four times what the World Health Organisation (WHO) - recommend as safe. And that's dangerous.

Here's how eating sugar, especially too much of the added sugar that's not naturally found in foods, affects your body:
